Nearly three pounds of the drug were inside a fire extinguisher in the back seat of the 1995 Jeep Cherokee, and the rest was in a modified motorcycle battery, Border Patrol spokeswoman Mary Beth Caston said.

Agents searched the SUV about 5:45 p.m. after a drug-sniffing dog reacted to it during a cursory inspection at the checkpoint on Interstate 5.

The driver, a 21-year-old U.S. citizen, was arrested. Both he and the drugs, which had an estimated street value of $139,000, were turned over to the U.S. Drug Enforcement Administration for further investigation, Caston said.
